Title: Viscous product dispenser having externally located, dispensed product shearing outlet valve provided with lost-motion action
Inventor: FOSTER DONALD D
IPC: B65D83/76
Filed: 1985-03-04
Abstract: The actuating lever 48 of the dispenser has an outlet valve flap 64 integral therewith which moves in a shearing action across the outlet of the discharge spout 38 as the actuator is returned to its standby position such that the returning valve flap cleanly slices through the bead of viscous product adhering to the spout and thus fully separates, the dispensed bead of product from that remaining behind in the spout. A lost-motion action permits the valve flap to uncover the spout outlet before ends 58 of actuator legs 52 contact body surface 60 and further depression of the actuating lever shifts the pumping piston 32 through its dispensing stroke to force product out the spout. The dispenser includes a spring 44 to return the piston 32 to its starting position after each dispensing stroke, and a follower piston 20 takes up the reduction in volume of the product. <IMAGE>

Patent GB-2179453-A (GB)
Title: Apparatus for detecting a changing magnetic field
Inventor: PATRICK PETER
IPC: G01R33/028
Filed: 1985-08-21
Abstract: The magnetic shielding effectiveness of an enclosure (3) for electronic equipment is tested using an instrument which includes a single closed loop conductor (1A) which fits inside the enclosure (3). A current sensor, preferably in the form of a toroidal coil (4A), senses currents included in this loop (1A) by a changing magnetic flux and the resulting output from the current sensor is measured by a voltmeter (5). The advantage of this arrangement is that the frequency response is a function principally of the current sensor design and the internal resistance of the voltmeter (5). These can be of fixed designs whilst the shape and size of the loop (1A) can be different in different instruments to allow it to fit into a container (3) at different orientations whilst always maximising the size of the loop (1A) and therefore the sensitivity of the instrument. <IMAGE>

Title: Arbitrary shape clipper
Inventor: TREVETT NEIL FRANCIS
IPC: G09G5/36
Filed: 1988-03-23
Abstract: A system and method for performing image clipping is disclosed. The system includes a RAM based clipper which can clip image data automatically, to arbitrary shapes, without the use of manipulative software. The preferred embodiment of the present system includes image clipping logic in the form of an Arbitrary Shape Clipper (ASC) 112. The ASC reduces image clipping time and allows for complex window management. In its preferred embodiment, the ASC includes a random access memory (RAM) which is used to store a bit mapped pattern defined by the shape of the non-obscured portion of a displayed window. The ASC uses this pattern to automatically clip (in gate 114) an image to the contours of the non- obscured portion of the window by write disabling the screen refresh memory 102 for addresses corresponding to any obscured portions of the active window. Advantageously, the use of a RAM stored, bit mapped pattern allows an image to be clipped, almost instantaneously, to even arbitrary and complex contours. <IMAGE>
